With this arrangement, rurli ratation 0fthe'pewer shaft 40 causes me complete vertical reciprocatinn of theplunger, and thereby depresses the press-er 10H yield ingly through theagency of the spring 104. The time relation which is preferred inprevail between the fel ier 83 11ml the presser 160 is such that theformer performs its often of turning ever the edge f the work more orless in advance of the descent of the presser to complete and press thefold; alas it i preferable that the felcler 85 dwell in its finalfolding pesition fer a. sllqrt period, so as tn maintain the fold inproper condition. awaiting the final action of the resser 100. Likewisethe folder 85 may retreat from active engagement with the Work beforethe resser is elevated #40 in active pnsitien.

Referring now t0 Fig. 3 the folder 85 preferably arts close along sidethe gmesser 100 end the latter may have a projecting p rtion givin itspressin surface a near approachto t e feed whee 24 and increasing itseffective area. It is frequently desirable to employ snipping. orslitting menus to make cuts in the edge of the work to provide againstcrimping or pocketing in folding a curved edge, as is well understood inthe art. The present illustrative machine is provided with snippingmeans exemplified y a knife 120, shown in Figs. 1, 3 and 1.2.

Referring now to Figs. 1 and 12, the cut-- ting edge ofthe knife 120 isinclined so as to be parallel to part of the face of the plow 75, thelatter conveniently serving a cutting bed. As presently described, theknife moves preferably in a path at an anglerto its cutting edge and thecutting bed as, for in stance, in a, vertical path in Fig. 1. There--by, the knife may be caused to out obliquely through the work from onesurface to the other, so as to give a species of drawing cut, whichmakes a cleaner slit and occasions less wear on the knife. Thatparticular part of the low 75 which is utilized as a cutting bed isinclined, and to suit this inclinati n the knife is set obliquely in itsholder. As shown in section in Fig. 9, the knife shank 120 rests in adovetailed seat supplied upon one side by part of the knife plunger andu on the other side by a removable clamping etc 121 and held in place bye. screw 122. n the specific machine as in other machines of the samegeneral. type already known in the art the edge of the work isordinarily artially turned over at the time when the nife acts. Usuallyalso that part of the work edge which is cut by the knife is somewhatlifted from the plane of the body of the work. Under such circumstances.if the cutting bed he in the plane of the work body. as on the worksupporting table, the snip )ing operation will tend to pull down andllatten the work edge against the cutting bed, thereby stretchmg theedge. To express it diiferently part of the edge havmg been turned overand pressed down, the remainder of the edge turned with a progresivelylessening curve toward the flat unfolded part of the edge. if the knifeoperates to out against a bed in the plane of the body of the work atany point between the flat unturned edge and the completely folded partof the edge, the partly lifted edge forced back upon the bed and inaccommodating itscll' to such a position the Work is stretched. This isespecially true if the knife b dull. in which case it exerts a pull onthe stock bef re melting its incision. When thus stretched, For examplewhen Working n a ramp throat... the edge of the thr at longer than it isinto-vied to be and is likely to pucker in assembling ilsc ramp andquarters.

The above described diiiiculties are avoided in the machine of thedrawings, by having the cutting bed inclined to suit the lifted orpartially turned position of the Work edge prevailing at the oint wherethe knife acts. Thus the Work e go is supported in its natural position,so that no stretching re sults. By this means the Work edge may be cutclose to the completed fold, if desired, even thogh the ed e may be veryconsiderably raised above t e plane of the body of the work. This admitsof a very compact organization of the machine, which is of coursedesirable. The upper part of the knife piun er may consist of a. sleeve12% encircling t e plunger proper 126. Between appropriate shoulders onthe sleeve 124 and plunger 1:26 is interposed a compression spring 1127which holds the upper extremity of the sleeve, against the head of ascrew 128 threading into the plunger 126. As the plunger movesvertically downward, 'the knife carried on the sleeve 124 is forcedrigidly to its cutting operation. by the head of the screw 128, but forpurposes of adjustment the spring 1.2? causes the sleeve and kui in tofollow the screw 128 as it is turned upwardly and downwardly on theplungcr E26. 7

Ho ferriog now to Fig. 2, the plunger 126 suitably mounted for verticalmovement in the main frame casting along side the presser plun er 106.The knife plunger is normally up ield by a compression. spring 130interposed between part of the frame and a collar on the plunger; andsaid spring serves tohold a. second collar 131 up against part of theframe which determines the uppermost limit of movement of the plungcr.To give the plunger 126 and knife the desired vertical reciprocation forcutting, the plunger 126 may be connected to the presscr plunger 106which is preferably continuously reciproceted and supplies a convenientsource of power. For this purpose, the casting 107 of the Jlunger 106has a heel 133 iirojecting laterally toward. the knife plunger 126 inposition to engage a. spring latch 135 on the latter. This latch isseated in a radial recess in the plunger 126 and is pressed outwardlytherefrom by a spring (not shown} except when prevented us presentlydescribed. Thus. in Fig. 2, when the heel 135i descends in the movementof the Presser, it may strike against the lower tooth of the latch 13:)and carry down the knife plunger 126 and knife against the tcnsion ofthe spring 130. it is not always nccosr-iary to slit an edge to befolded, and at timer. the knife or other shipping means may well beidlv. For example, in folding a shoe vamp, it is not necessary to snipany part. usually. except the throat. Accordingly it is com'enient tosup ly means for interrupting the operation of the knife at will.
